BestAir HW-series replacement media filter for whole-house air cleaner cabinets, designed to fit compatible Honeywell air cleaner models. The deep-pleat design packs a large media area into the cabinet, so the filter holds far more dust than a 1-inch panel filter and runs up to 12 months between changes.
